Direct Coupled Damper Actuator
Model MY6050A1001
General
Model MY6050A1001 direct coupled damper actuator is a
motorized actuator to open/close a damper. Model
MY6050A1001 provides 2-position or floating control in
response to a command from a controller. Combined with a
Model QY9010A1014 auxiliary potentiometer, Model
MY6050A1001 provides proportional control in response to a
command from a proportional controller.
Features

Installation
CAUTION

•To prevent product damage, always disconnect
the power supply from the product before
performing installation.
IMPORTANT:
•
A
void application that keeps product operating
cycle excessively frequent.
•Meet the rotating direction of the actuator with the
damper rotating direction.
•Tighten the screws so that the actuator is securely
assembled with the damper.
•For the product installation, secure maintenance
clearance shown in Fig. 1.
Installation procedure
1) Fully close the damper shaft.
Figure 4. Damper shaft
2) Fully close the actuator Model MY6050A, and mount it
to the damper shaft. Finger-tighten the fastening nuts of
the shaft clamp to temporarily fix the actuator.
Figure 5. Temporal installation of the actuator body
3) With the gear release button pressed , manually rotate
the shaft clamp until it is in the position shown in Fig. 6.
Then, insert the universal bracket into the slit of the
actuator and fix the bracket onto the damper with the two
M4 tapping screws.
Figure 6. Attaching the universal bracket
4) Manually rotate the shaft clamp back to the fully closed
position with the gear release button pressed. At this
time, be sure to leave a clearance (approx. 1 mm)
between the shaft clamp and the rotation angle adjuster
(mechanical stopper). Using a wrench, tighten the
fastening nuts of the shaft clamp to completely fix the
actuator.
Figure 7. Complete installation of the actuator body
5) Attach the position indicator ring to the damper shaft so
that the tip of the damper blade and the pointer of the
indicator ring point to the same direction.
Adjust the rotation angle adjuster on the fully open side
depending on the damper rotating angle.

IMPORTANT:
•For Model R30/R31/R35/R36/SDC40 single loop controller (Model with MFB* input) connected to Model
MY6050A1001, automatic setting function of feedback potentiometer is not available. Manually perform the
potentiometer setting. ∗MFB: Motor feedback
•For the controller with time-limit feedback connected to Model MY6050A1001, error may be detected. In such
a case, reset longer time limit.

Connection example for multiple actuators (in parallel operation)
Precautions for parallel operation
•Confirm the total power supply voltage of the actuators to operate in parallel.
•Operating time of each damper may differ due to error. This may result in difficult synchronization of the actuators
operation.
•Parallel operation of the multiple actuators may affect the operation life of the controller contact.
•Due to different operating time, Model MY6050A actuators cannot be combined with Model MY6040A actuators.
